Class 10 Science Chapter 12 Notes: Electricity Revision

followed by ‘Fundamental Laws of Electrostatics’, ‘Coulomb’s Law’ and ‘Conductors & Insulators’.

Start with the definition of Electricity and  Frictional Electricity.

Next, learn about the definition of ‘Current’, its SI unit and practice some example problems using its mathematical expression.

The following essential topics are - Electric Potential Energy, Ohm’s Law, Resistance & Factors affecting the Resistance.

Study what is Resistivity & Conductivity. Learn how the temperature affects resistivity.

Semiconductors and Superconductors, Resistance in Series and Resistance Parallel should be learnt in detail.

Heating Effect of Electric Current, Joule’s Law of Heating & problems on these are also important.

Also, learn Applications of the Heating Effect of Electric Current and what a ‘Fuse Wire’ is and its uses.
